Forest experiments were run using the Lush
interface to the LASVM code.

The la_svm driver cannot run these experiments
because we have used a specialized kernel with 
considerable speed optimizations.

File forestkernel_code.c implements this kernel.
It provides two functions:
  forest_class(i) to know the class of example i
  forest_kernel(i,j) to compute the kernel K(i,j).

Prior to calling these functions, the contents 
of file "forest-short-581012x13.raw" must be
loaded into array <forestdata>.

Examples 0 to 49999 were used for testing.
Examples 50000 to 59999 were used for cross-validation.
The training set starts with example 60000.

We do not recommend running experiments
on this database because its preprocessing,
centering and normalizing each continuous
variable, is inadequate and does not yield
the best performance.
